Abstract (en)
[origin: EP3785918A1] A valve device includes a flow channel section where fluid flows, a reserving section that reserves fluid from the flow channel section, a valve that switches between opening and blocking of the fluid flow in the flow channel section based on an operation signal, and a determination section that determines a deterioration degree of the valve on a basis of an operation of the valve based on the operation signal and of pressure in the reserving section.
